Introduction

Satellite Launch Statistics: ​Satellites serve critical functions, including technology development, Earth observation, communications, space science, and navigation. These artificial objects are launched into space aboard rockets and positioned in various orbits—low Earth orbit (LEO), medium Earth orbit (MEO), and geostationary orbit—depending on their intended applications.

As of June 2024, approximately 11,780 satellites were orbiting Earth. The number of satellites launched annually has surged, with 2,664 objects sent into space in 2023, breaking the previous year's record. This increase is largely driven by the deployment of large constellations, such as SpaceX's Starlink, which alone accounted for around 3,500 satellites between 2020 and 2022. The proliferation of satellites underscores their growing importance in advancing global technological capabilities.

As of November 2024, the United States accounted for 8,530 satellites in orbit, the highest number of any nation or organization. Many of these satellites belong to private U.S. organizations such as SpaceX's Starlink, which provides satellite internet services via a constellation of low earth orbit (LEO) satellites.

Background

Within the past two decades, the number of resident space objects (RSOs - artificial objects that are in orbit around the Earth) has nearly doubled, from around 11000 objects in the year 2000 to around 19500 objects in 2019. This number is expected to rise even higher as more satellites are put into space, thanks to improvements in satellite technology and lower costs of production. On the other hand, the increase in the number of RSOs also indirectly increases the risk of collision between them. The important issue here is the reliable and accurate orbit tracking of satellites over sufficiently long periods of time.

Failure to address this issue has led to incidents such as the collision between the active US Iridium-33 communication satellite, and the inactive Russian Kosmos-2251 communication satellite in February 2009. In fact, this accident increased the amount of space debris by 13%, as shown in the figure below:

https://orbitaldebris.jsc.nasa.gov/_pictures/leo-objects-graph.png" alt="Number of space objects in Low Earth Orbit (NASA, 2019)">

More accidents will result in more debris being produced, and through a chain reaction of collisions (if left unchecked), may lead to a dire situation in which it becomes difficult or downright impossible to put a satellite into orbit due to the large accumulation of space debris surrounding the Earth. This scenario is known as the Kessler Syndrome. Thus, considering the gravity of the situation at hand, it is imperative to prevent such catastrophic collisions from ever happening again.

Context

The aim is to use machine learning or other forecasting algorithms to predict the positions and speeds of 600 satellites in orbit around the Earth. The original datasets were obtained from the International Data Analytics Olympiad 2020 (IDAO 2020) Competition, provided by the Russian Astronomical Science Centre. Being a competition, IDAO does not provide the answer key for their test dataset. However, I prepared their train dataset in such a way that testing one's algorithm can easily be done via the answer_key. This preparation is outlined in the notebook associated with this dataset ("Data Preparation to Produce Derived Datasets").

Satellite positions and speeds (henceforth, they will be collectively referred to as the "kinematic states") can be measured using different methods, including simulations. In this dataset, there are two kinds of simulators: the precise simulator and the imprecise simulator. We refer to measurements made using the precise simulator as the "true" kinematic states of the satellite and measurements made using the imprecise simulator as the "simulated" kinematic states.

The aim is to make predictions for the true kinematic states of 600 satellites in the final 7 days of January 2014.

Datasets Description

• The jan_train dataset contains data on both true and simulated kinematic states of 600 satellites for the 24-day period of time from 01-Jan-2014 00:00 to 24-Jan-2014 23:59.
• The jan_test dataset contains data on only the simulated kinematic states of the same 600 satellites for the final 7-day period of time from 25-Jan-2014 00:00 to 30-Jan-2014 23:59.
• The answer_key dataset contains data on only the true kinematic states of the same 600 satellites for the final 7-day period of time from 25-Jan-2014 00:00 to 30-Jan-2014 23:59. NOTE: The answer_key should only be used for the purpose of evaluation, NOT for training.

Variables Description

• id (integer): unique row identifier
• epoch (datetime): datetime (at the instant of measurement) in "%Y-%m-%d %H:%M:%S.%f" format (e.g. 2014-01-27 18:28:18.284)
• sat_id (integer): unique satellite identifier, ranging from 0 to 599
• x, y, z (float): the true position coordinates of a satellite (km)
• Vx, Vy, Vz (float): the true speeds of a satellite, measured along the respective axes (km/s)
• x_sim, y_sim, z_sim (float): the simulated position coordinates of a satellite (km)
• Vx_sim, Vy_sim, Vz_sim (float): the simulated speeds of a satellite, measured along the respective axes (km/s)

Tasks

1. Start by exploring the dataset as a whole, getting familiar with the data contained within.
2. Choose one satellite to explore in more detail, looking at both true and simulated kinematic states
3. Look at the periodicity and pattern of each kinematic state, and think about whether or not they will be useful in a predictive model.
4. Develop a machine learning model to forecast over the final 7 days for each kinematic state of the chosen satellite.
5. Repeat the process for the remaining 599 satellites, keeping in mind that there could be differences between them. Otherwise, choose the satellites that are most interesting or those that are quite different from each other.

...

As of the end of 2022, over ** percent of active satellites were in low Earth orbit (LEO), while around **** percent were in geostationary (GEO) orbit. LEO satellites typically orbit less than 1000 kilometers above the earth’s surface, and so can service a range of applications not viable at higher altitudes. Starlink expands its LEO constellation While satellite imaging has long been a core function of LEO satellites, a recent surge in LEO launches has been driven by satellite internet providers, with low orbits allowing the provision of fast internet with minimal latency. Satellite internet operators deploy multiple satellites in so-called constellations, which allow the coverage of broad regions around the clock. SpaceX’s Starlink has invested heavily in its LEO constellation, with the firm accounting for more than a ***** of all active satellites in orbit as of October 2023. The FSS market faces oversupply Orbiting at an altitude of almost 36,000 kilometers, GEO satellites precisely match the rotation of the Earth, and so appear to remain stationary relative to the Earth’s surface. This enables GEO satellites to remain in constant contact with fixed locations. GEO satellites serve a range of fixed-service satellite (FSS) applications, including traditional telecommunications broadcasting, but cannot match the low latency offered by LEO services. The global FSS market generated over *** million U.S. dollars in 2022 but faces pressure in the form of increased supply driven by the rise of satellite internet operators.

SEA Icosaedro simulations

May and June 2020

For the moment, all of them are based on the constellation profile starlink.dat, that considers some 12 thousand satellites.

File: bv2020_microsatelites.pdf, report published in the Butlletin of the Spanish Astronomical Society (in Spanish language)

All these tests include a photometric model of intermediate complexity, that takes into account distance to the observatory, phase angle, extinction (0.12 mag/airmass was selected for this bunch of simulations) and geometry of the shadow cone of the Earth. This model is very similar to that of Hainaut & Williams (2020) and our results may be directly compared to theirs.

Affectation depends on the observatory latitude, but not on longitude. However, the main factors are the width of the field of view (FOV) and integration time (T). We performed tests for several different observatories available to the SEA community and this certainly illustrates latitude effects, but our results underline the strong importance of FOV and T and they are useful mainly to analyse these factors.

Observatories and latitudes (degrees):
Calar Alto +037
Javalambre +040
La Palma +029
Montsec +042
Paranal -024

For each observatory (i.e., each latitude) we perform simulations of two kinds:

1) All-sky simulations:

Counting the number of satellites visible as a function of time along one complete night

--> For five different Sun declinations: +023, +012, +000, -012, -023 degrees

--> For two different elevations over the horizon: satelites visible above +000 deg, and above +030 degrees

So, in total, ten simulations are done at each location.

File naming conventions:

S_+LLL_+DDD_+HHH_NNN.xxx

S: means "Starlink"
+LLL: observatory latitude, degrees
+DDD: Sun declination, degrees
+HHH: Elevation over which satellites are counted, degrees
NNN: Number of individual interations that are averaged out (050 in all cases)
xxx: Type of file:

xxx = jpg, ps, pdf, graphs with number of visible satellites as a function of time, time is measured from the previous noon and is given in mintutes, vertical lines indicate the instants of beginning and end of civil, nautical and astronomical twilights, and midnight.

xxx = mp4, animation with the apparent magnitude histogram of visible satellites at one minute steps; background colour means: white in daylight, grey in civil twilight, light blue in nautical twilighg, deep blue in astronomical twilight, black during astronomical night

xxx = dat, files with very detailed information about the simulation, not included here, but may be provided, with indications about their contents

Example:

S_+037_+012_+030_050.mp4

S: Starlink
+037: Calar Alto latitude
+012: Solar declination intermediate north +12 degrees
+030: Counting satellites at 30 deg or more above horizon
050: 50 simulations were averaged
mp4: Movie with the histogram of apparent magnitudes

2) Pointing-oriented simulations:

We select a FOV in arcminutes and an integration time T in seconds. Then, five observing directions are predefined:

N, S, E, W at 45 deg elevation, and zenith

For the given latitude we select Solar declination (0, +23, -23) and, both fixed, we study the five fields of view for three different solar elevations: -12, -25, -37, both PM and AM.

This means that for one given observatory (latitude, FOV, T), 5 x 3 x 3 x 2 = 90 configurations, see:

5 pointing directions
3 solar declinations
3 solar elevations
2 for am/pm conditions

This produces quite a large amount of information that is organised in form of detailed files and summary tables.

Detailed files are:

P_+LLL_+DDD_+HHH_pm_+aaa_+hhh_FOVi_iTim_NCRO.dat
p_+LLL_+DDD_+HHH_pm_+aaa_+hhh_FOVi_iTim_NCRO.dat

P: very detailed output, p: less detailed output
+LLL: observatory latitude
+DDD: Sun declination
+HHH: Sun elevation
pm = "pm" or "am"
+aaa: observation azimuth from the South (O = S; 90 = W, 180 = N, 270 = E)
+hhh: observation elevation (45 deg for NSEW, 90 deg for Z)
FOVi: field of view in arcminutes
iTim: integration time in seconds
NCRO: number of crossing (multiple shots are simulated until NCRO sat crossings are registered, or until 1000 shots have been simulated)

Detailed files are probably intersting only for very technical analysis, so they are not included here, but they may be provided upon request.

The main results are contained in pdf tables that are, hopefully, self-explaining.

The growth of the market is primarily driven by demand for efficient and high-resolution satellites with advanced capabilities such as remote sensing and surveillance, navigation, and scientific research applications.

Satellite payloads are the different components or functionalities onboard a satellite that enables it to perform specific functions. These functionalities include sensors, transmitters, and transceivers for communication purposes, etc. The main function of these devices is to receive signals from one point on earth and then transmitting them back to another location in order to provide information regarding any particular region.

On the basis of Type, the market is segmented into LEO (Low Earth orbit), GEO (Geosynchronous Earth orbit), MEO (Medium Earth orbit).

LEO (Low Earth orbit):

LEO is a type of low Earth orbit satellite that can be placed into space from the surface of our planet. It has a high orbital speed and its height above sea level varies between 160 kilometers (100 miles) to 2000 kilometers (1250 miles). Because it orbits relatively close to the earth’s surface, LEO satellites stay in sight only for several minutes before they pass over the horizon. This makes them unsuitable for certain applications such as communication where connections need to be maintained over long periods because tracking would have been lost during brief periods when there was no line-of-sight with an antenna on Earth.

GEO (Geosynchronous Earth orbit):

A GEO is an orbit around Earth with an altitude of about 35,786 kilometers (22,236 mi), and an orbital period equal to the time it takes for a satellite in that orbit to complete one revolution around the planet. This allows satellites to maintain a geostationary position relative to a fixed point on Earth’s surface. This allows uninterrupted coverage of most parts of the world by communication and Remote Sensing Satellites.

MEO (Medium Earth orbit):

Medium Earth orbit (MEO) is a type of intermediate circular orbit (ICO) around the Earth above low earth orbit (LEO). Observations from MEO are useful for some orbital operations and data collection. MEO (Medium Earth orbit) is a type of satellite that orbits between MlO and 20,000Km above the earth’s surface. It takes 96 minutes for satellites in this orbit to complete one full revolution around the earth.

On the basis of Application, the market is segmented into Telecommunication, Remote Sensing, Scientific research, Surveillance, and Navigation.

Telecommunication:

Satellite payloads are generally used in telecommunication applications. These satellites serve as communication relay stations. Furthermore, satellite networks help the users to exchange voice and data through their terminals (e.g., hand-held devices). Satellite payloads enable communication via space-based networks using satellites. These satellite-based communication systems provide faster data exchange capabilities with low latency rates to users on land, sea, or air allowing them uninterrupted access at all times.

Remote Sensing:

Satellite payloads are used for various applications in the remote sensing industry. These include weather forecasting, earth observation & imaging, search and rescue operations, etc. Satellite payloads are used for imaging the earth from a distance. In fact, there has been an increase in demand of high resolutions satellite images that can be used to map and monitor various geographical areas across the world.

Scientific research:

Satellite payloads can also be deployed for scientific purposes such as monitoring environmental changes etc. They could even pinpoint an area that needs attention by sending images or other relevant information about it back home to scientists studying them closely from earth orbit/orbiters who need this kind of data badly for their study results which cannot be gathered with ground-based measurements alone because they will not give you enough spatial coverage due to a limited number of sensors on Earth's surface at any point in time.

On the basis of Region, the market is segmented into North America, Latin America, Europe, Asia Pacific, and the Middle East & Africa. The North American region holds a significant share in the global satellite payloads market. Latin America is projected to grow at a faster rate due to the growing dema

While the initial investment costs can be a restraint, the long-term operational and data acquisition benefits are compelling investors and governments alike. Regionally, North America and Europe currently dominate the market due to established space infrastructure and a strong technological base. However, Asia-Pacific is showing significant growth potential, fueled by increasing investments in space exploration and communication infrastructure within nations like China and India. Competition within this segment is fierce, with major players including Airbus SE, CASC, ISRO, Northrop Grumman, OHB SE, Roscosmos, and Thales vying for market share. The forecast period of 2025-2033 suggests continued substantial growth for the mid-size satellite market, with a projected CAGR (Compounded Annual Growth Rate) likely in the range of 8-10%, depending on technological advancements and global economic conditions. The market will witness the further adoption of electric propulsion systems, leading to increased mission duration and operational efficiency. The emergence of innovative business models, such as satellite-as-a-service, will also play a significant role in driving market expansion. Challenges remain, however, including regulatory hurdles, launch costs, and the need for robust space situational awareness to manage the growing number of satellites in orbit. Nevertheless, the market outlook is optimistic, with substantial opportunities for growth and innovation in the coming decade.

This dataset consists of ground-based Satellite Laser Ranging observation data (normal points, daily 24 hour files) from the NASA Crustal Dynamics Data Information System (CDDIS). SLR provides unambiguous range measurements to mm precision that can be aggregated over the global network to provide very accurate satellite orbits, time histories of station position and motion, and many other geophysical parameters. SLR operates in the optical region and is the only space geodetic technique that measures unambiguous range directly. Analysis of SLR data contributes to the terrestrial reference frame, modeling of the spatial and temporal variations of the Earth's gravitational field, and monitoring of millimeter-level variations in the location of the center of mass of the total Earth system (solid Earth-atmosphere-oceans). In addition, SLR provides precise orbit determination for spaceborne radar altimeter missions. It provides a means for sub-nanosecond global time transfer, and a basis for special tests of the Theory of General Relativity. Analysis Centers (ACs) of the International Laser Ranging Service (ILRS) retrieve SLR data on regular schedules to produce precise station positions and velocities for stations in the ILRS network. The daily SLR normal point observation files contain data received in the previous 24-hour period from a global network of stations ranging to satellites equipped with retroreflectors. Data are available in ILRS data format (older data sets) and/or the Consolidated Ranging Data (CRD) format. More information about these data is available on the CDDIS website at https://cddis.nasa.gov/Data_and_Derived_Products/SLR/Normal_point_data.html.
